An analytical technique that is used in solving paternity dispute based on DNA polymorphism is called :

Options

A. Cloning
B. Cell culture
C. DNA sequencing
D. DNA fingerprinting

Answer

To solve the question regarding the analytical technique used in solving paternity disputes based on DNA polymorphism, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for an analytical technique used in paternity disputes that relies on DNA polymorphism. This indicates that we should look for a method that analyzes variations in DNA sequences.

**Hint**: Focus on techniques that analyze DNA variations.

2. **Identifying Relevant Techniques**: There are several techniques in molecular biology that can analyze DNA, but we need to identify which one specifically relates to paternity testing. Common techniques include DNA sequencing, cloning, and DNA profiling.

**Hint**: Think about techniques specifically used for identifying individuals based on their DNA.

3. **Recognizing DNA Profiling**: The technique that is most commonly associated with paternity testing is DNA profiling, also known as DNA fingerprinting. This method compares specific regions of DNA that are known to vary among individuals.

**Hint**: Recall that DNA profiling is often used in forensic science and paternity testing.

4. **Understanding the Mechanism**: DNA profiling often employs techniques such as Polymerase Chain Reaction (PCR) and Restriction Fragment Length Polymorphism (RFLP) to analyze DNA samples. These methods help in identifying whether an individual is a biological parent by comparing DNA patterns.

**Hint**: Consider the techniques that provide a unique pattern for each individual.

5. **Eliminating Incorrect Options**: The other options provided (cloning, cell culture, DNA sequencing, and somaclonal variation) do not specifically relate to paternity testing. Cloning is about creating a genetically identical copy, while cell culture pertains to growing cells in a controlled environment. DNA sequencing provides the order of nucleotides but does not focus on polymorphisms for individual identification.

**Hint**: Eliminate options that do not directly relate to identifying biological relationships.

6. **Final Answer**: Based on the analysis, the correct answer to the question is **DNA fingerprinting**.

### Final Answer:
The analytical technique used in solving paternity disputes based on DNA polymorphism is called **DNA fingerprinting**.
